Overlay of initial yerba mate extract fraction chromatograms.

<p>A) The black chromatogram corresponds to a yerba mate extract fraction that demonstrated antibacterial activity against methicillin-resistant <i>Staphylococcus aureus</i> (MRSA); the red chromatogram corresponds to a yerba mate fraction that had no antibacterial activity against MRSA. B) Retention times of identified compounds and quantification in sorbitol equivalents were reported.</p

Top 20 unique retention times ranked by antimicrobial significance against MRSA using random forests.

Growth of methicillin-sensitive (SA) and methicillin-resistant <i>Staphylococcus aureus</i> MRSA) in the presence of pure compounds.

<p>At concentrations of 10 μg/ml (chemical_1), 20 μg/ml (chemical_2) and 100 μg/ml (chemical_3), growth with compounds was compared to the positive growth control (no chemical added) to determine inhibitory activity. Statistically significant differences greater (*) or less (**) than control are marked by asterisks. Growth of A. SA 113, B. SA 27708, C. MRSA 35591, and D. MRSA 35593 are reported at 48 h. SA113 had a significant block by treatment interaction, so no conclusions can be drawn from it.</p
